Abstract
A radioactive substance absorber is incorporated into an intravascular radiotherapy source ribbon assembly to prevent the migration of radioactive matter throughout the assembly container. The radioactive substance absorber comprises carbon in various forms and configurations. The radioactive substance absorber is positioned in proximity to the source core and absorbs radioactive materials which break free from the source core, thereby containing the radioactive material.
Claims12
A method for the containment of radioactive substances in an intravascular radiotherapy source ribbon assembly comprising:
- positioning a radioactive substance absorber in proximity to a radioactive source core, including disposing a carbon fiber layer sheath over the radioactive source core;
- and
- sealing the radioactive substance absorber and radioactive source core in a flexible, radiation transparent container of the intravascular radiotherapy source ribbon assembly.
An intravascular radiotherapy source ribbon assembly comprising:
- a sealed, elongated flexible tube defining an interior cavity;
- a radioactive source core disposed within the interior cavity;
- and
- a radioactive substance absorber disposed in proximity to the source core to absorb stray radioactive matter, around the radioactive source core the radioactive substance absorber comprises a carbon
- fiber layer disposed around the radioactive source core.
